Optical SpecificationsFigure 5.1:8080 System Bus TimingNOTE (1)Definition of Contrast Ratio(CR):The contrast ratio can be calculated by the following expression. Contrast Ratio (CR) =L63 / L0L63: Luminance of gray level 63L0: Luminance of gray level 0CR = CR (10)CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (6).14

Formike Electronic Co.,Ltd.Note (2) Definition of Response Time (TR, TF):Model No.:KWH028Q06-F02Note (3) Definition of viewing Angle:*** The above “Viewing Angle” is the measuring position with Largest Contrast Ratio; not forgood image quality.View Direction for good image quality is 6 O’clock. Module maker can increase the “ViewingAngle” by applyingWide View Film.15

Formike Electronic Co.,Ltd.Model No.:KWH028Q06-F02Note (4) Measurement Set-Up:The LCD module should be stabilized at a given temperature for 20 minutes to avoidabrupt temperature changeduring measuring. In order to stabilize the luminance, the measurement should be executedafter lighting Backlight for20 minutes in a windless room.Note(5)16

Formike Electronic Co.,Ltd.Model No.:KWH028Q06-F027. Reliability Test ItemsReliability Test Criteria:Display function should be no change under normal operating condition.8. Package(TBD)9. Handling Precautions9.1 SafetyThe liquid crystal in the LCD is poisonous. Keep away from your mouth and eyes. If the liquidcrystal contacts with your skin, mouse or clothes, use soap to wash it off immediately.9.2 Handlingi. The LCD panel is made by thin glass. Prevent the panel from mechanical shock or puttingexcessive force on its surface.ii. The polarizer attached on the display is very easy to be damaged, handle it with specialattention.iii. To avoid contamination on the display surface, do not touch the display surface with barehands.iv. The transparent electrodes may be disconnected if you use the LCD panel under17

dew-condensing environment.v. The characteristics of the semiconductor devices may be affected when they are exposed tolight, possibly resulting in malfunctioning of the ICs. To prevent such malfunctioning of theICs, make sure the application and the mounting of the panel are designed so that the IC is notexposed to light.9.3 Static ElectricityGround soldering iron tips, tools and testers when you operate. Also ground your body whenhandling the products and store the products in an anti-electrostatic container.9.4 StorageStore the products in a dark place where the temperature is within the range of 25±10 and withlow humidity (65%RH or less). Do not store the LCD product in an atmosphere containingorganic solvents or corrosive gases.9.5 CleaningFormike Electronic Co.,Ltd.Model No.:KWH028Q06-F02Do not wipe the polarizer with dry cloth, as it might cause scratching. Wipe the polarizer with asoft cloth soaked with petroleum IPA. Other chemical might damage the panel.18
